WHEEL-HUB.

$PECI-FIOATION forming part of Letters Patent No. 689,019, datedDecember 17, 1901.

Application filed July 17, 1901.

To (tZZ whom it may concern:

Be it known that I, A DOLPHUS PATNODE, a citizen of the United States,residing at Alpena, in the county of Alpena and State of Michigan, haveinvented new and useful Improvements in Wheel-Hubs, of which thefollowing is a specification.

My invention relates to improvements in wheel-hubs of the type whichembody antifriction-rollers and it consists in a certain peculiarconstruction the novelty, utility, and advantages of which will be fullyunderstood from the following description and claim when taken inconjunction with the accompanying drawings, in which-- Figure l is asectional view with some of the parts in elevation, illustrative of myimproved hub in its proper operative position on an axle of the usualconstruction. Fig. 2 is a transverse section taken in the planeindicated by the line X X of Fig. 1 looking in the direction indicatedby arrow, and Fig. 3 is a side elevation of one of the annular disksemployed in the hub.

Similar letters of reference designate corresponding parts in all of theseveral views of the drawings, referring to which- A is an axle, thespindle A of which has the usual collar (1 at its inner end and threadsZ; at its outer end, and B is the body of my improved hub. This body maybe and preferably is cast of iron or other metal suitable to the purposeand is exteriorly threaded at its inner and outer ends, as indicated byc and (1, respectively, and provided at opposite sides of its middlewith peripheral apertured flanges e,thelatter for the connection ofspokes. (Not shown.) Interiorly the body is provided with an annularflange f, which occupies its transverse center, and turned bores g,which extend from the flangef to'its opposite ends and are of evendiameter throughout.

C is a dust-guard screwed on the inner end of body B and looselysurrounding the axle at the inner side of the collar a; D, a circularnut of slightlyless diameter than the outer bore g of the body, arrangedin said bore and on the threaded end of the axle-spindle; E, a capscrewed on the outer end of the body to exclude dust from the interiorthereof, and F F annular apertured disks, of which four are employed.These disks are disposed as Serial No. 68,686- (No modelshown-21 8., twoare arranged at opposite sides of the interior flangefof the body, oneat the outer side of the collar a and one at the inner face of the nutD. Their apertures 7t receive the ends of shafts G, which are pref,-erably of steel, and on the said shafts are loosely mount-edantifriction-rollers ll, of steel or other suitable metal, which areinterposed between the disks and also between the axlespindle and thehub. The diameter of the said rollers H is slightlygreater than the width of the flangefand disks F, and consequently it will be seen that saidflange and disks are prevented from contacting with the axle-spindle andcreating friction when the hub is turned thereon.

It will be readily appreciated from the foregoing that the two circularseries of rollers H, disposed at opposite sides of the flange in thehub-body, will bear and roll on the axle-spindle and aiford long rollingsupports for the hub-body, with the result that the Wheel, of which thehub is designed to form a part, will be held in its true position, andfriction incident to the rotation of the hub will be reduced to aminimum; also, that the construction of the hub as a whole is verysimple and compact, and the parts are adapted to be quickly and easilyassembled on the axle. It will fur ther be appreciated that by virtue ofthe guard C and cap E dust is practically precluded from gaining accessto the interior of the hub and causing frictional wear of the parts.

By reason of the rollers H being loosely mounted on the shafts Gfrictional wear is removed from the disks F, and said disks maytherefore be formed of cast-iron or other comparatively cheap metal-thiswith a view of diminishing the cost of the hub as a whole withoutdetracting from its durability.

The dust-guard C may be formed in sections welded together on the axleat the inner side of the collar to or may be secured on the axle andnnt, rods conneeting'the disks, and antifriction-rollers mounted on saidrods and ini0 terposed between the disks.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

ADOLPHUS PATNODE.
